With the Smart Shield applicator, everything has been designed for your convenience. The ergonomic, contoured shape grants you an enhanced grip. The tip has a fin that helps to spread your cat's hair for effective application directly onto your cat's skin. With the liquid securely contained into the applicator, youíll ensure Bio Spotís treatment gets to your cat's skin, and nowhere else.

Protecting your cat from fleas and other pests not only relieves an inconvenience. Stopping fleas from constantly feeding on your cat can help stop flea allergy dermatitis. Repelling and killing mosquitoes can prevent the spread of heartworm disease.

With lanolin included in the formula, Bio Spot Defense helps condition your cat's coat when applied. It is also water resistant in humid and wet conditions.

Customer Reviews

Still seems like they are still scratching. Too much liquid in the dose. Ran way down their neck where they could scratch and lick it off of paws.

Works great by Heidicat from Bakersfield CA11/26/2013

We have used different flea treatments but they made our cats sick. We have been using Bio Spot and have no problems and works great. We use it for our dog also.

Bio-Spot for cats by Donna from Pa08/03/2012

I've owned cats for over 26 years and have tried alot of different products. None seem to work as well, and the more expensive brands don't work any better. I will not change again.

wasted my money by Unhappy customer from Salem, Oregon01/28/2015

I read all the good reviews and trusted what I read. I have two little 9# rescue lap dogs. Also a rescue cat. We put on the Bio spot Defense the first month. Still had flea so second month still had fleas. I'm very unhappy that this product does not work. If I could get my money back I would send the remander back.

Works solidly every time by Tabbigsby12/05/2012

Bio Spot has worked on our two shop cats for us for the last two years. It is economical and does its job.

Does Not Work by Moo from SF, CA03/02/2014

Three days after her flea shampoo treatment, I put the bio spot on my cat a few days ago and she still has fleas. It does not work! And I've vacuumed, laundered the bedding, and bombed the place etc. The only place the fleas are coming from is from her.

No effect by pigfan55 from Lake View, AL10/23/2012

I ordered the dog version and the cat version of this product and neither product had any effect on their fleas. My cats have scratched sores around their neck and I ended up going to PetSmart for Frontline for both cats and dogs. Just not good for Alabama fleas!
